You will be impressed by the high forward gain
and front to back ratio along with the sharp clean pattern of
this rugged low end of the band antenna
Antenna is constructed of the finest materials, 6061 aluminum
tubing and solid aluminum rods. (Reflector and director rods,
3/16"dia., driven element rod, 1/4" dia.) Main features
include T match system for balanced radiation pattern, coaxial
balun hardwired directly to the T match system. No coax connectors
to seal and water proof or to introduce losses. Ultra reliability.
Balun cable passes into the connection box via black delrin threaded
bushings.All connections housed inside machined aluminum box.
Shorting bars are new design with twin machine screws and nylon
stop nuts. Elements mounted on the boom using unique clamp design.
Clamps are machined from solid aluminum bar stock and when tightned
, clamp will compress around the element rod.Tolerences are very
close here with the rod making a precision fit withing the hole
bore. This method makes for a stiff and rigid antenna which is
a snap to assemble and take apart. All hardware is top quality
stainless steel except the U bolts which are zinc plated.
